CXCR4 protein expression was increased in eELCs under both normoxia (without DFO) and hypoxia (with DFO) conditions (a). Phosphorylated Akt (pAkt) was increased in MSCs under DFO treatment (b). eELCs showed higher protein expressions of pAkt, NFκB p65, and IκBα than MSCs regardless of DFO treatment. *Significant from MSCs under regular culture condition, p < 0.05. DFO desferrioxamine, MSC mesenchymal stem cells, eELC early endothelial lineage cells, CXCR4 C-X-C chemokine receptor type 4
